OPENHAUSdesign, based in Venice Beach, is the founding team of Cynthia Salah Kraus and Claudia Wiehen. The organic pairing of design sensibilities, and professional and life experiences brought us together to create a design firm where the livability of designed space and how it affects the natural environment is the desire that drives our work. Our firm name, OPENHAUS, reflects our values of client collaboration and experimentation.  We understand that light, air, color and texture are the tools in which spaces are created and experienced and that these tools are always evolving.

As hands on principals, we feel that great design ideas may begin with the sketch, but always ends in the constructed details. Luckily our love for a construction site, working with contractors, and truly listening to our clients, brings that extra needed step, bringing great buildings to fruition.


Cynthia Kraus, a native Angelino with a love of California architecture, comes to design and building with the belief that environmental responsibility should be brought to every aspect of living and much of her professional career has concentrated in the areas of sustainable design. She also brings 20 years of experience in project delivery and construction administration, with expertise in many project types, including residential and civic work. Cynthia received her Bachelor of Architecture from the University of Southern California in 1994. She is a licensed Architect in California, a member of the AIA and has been a LEED Accredited Professional since 2003.


Born and educated in Germany, Claudia Wiehen received her Interior Architecture degree from the Academy of Fine Arts in Munich. With her passion for mid-century modern architecture, Claudia moved to Los Angeles in 2002. She brings 15 years of experience to OPENHAUS in all design phases of residential projects, as well as offices, retail, and mixed-use projects. Brought up with very high design and environmental standards, Claudia implements minimal, functional, and sustainable design into our projects but works very closely with the client to achieve their goals, schedule and, foremost, their budget.
